    Abstract: A data synchronization method, system and apparatus are provided. The method includes receiving a request including data to be uploaded, from a client, and responding to the request after data is successfully obtained from the client, and storing the obtained data. For data whose size is less than a threshold value, a synchronization request is sent to a standby server to request the standby server to store the data. Otherwise a second type work log, including information indicating that data that has not been synchronized, is generated and stored. Data whose size is greater than or equal to the threshold value is not synchronized immediately, but is recorded in the work log. In some cases, data whose size is less than the threshold value, but fails to be synchronized, is recorded in the work log. Synchronization of this data may be subsequently completed according to the work log, so that the synchronization of this data can avoid affecting synchronization of other data.

  • Patent number: 10552322
    Abstract: Embodiments are directed to techniques for allowing a data storage system to be able to flush data to underlying storage when the bandwidth is high without excessively impacting the maximum latency. This may be accomplished by utilizing asynchronous flushing and by throttling incoming writes by preventing too many asynchronous flushes from happening when the amount of available cache space is too small. In addition, an improved system employing Copy on First Write (CoFW) may initiate write throttling only once the amount of available write cache drops below a dynamically-calculated threshold that accounts for an amount of space actually needed to store CoFW buffers. In addition, only a portion of the write caching process is placed under the protection of a mutex or a spinlock, allowing a significant portion of the write caching for any given write operation to be performed without needing the mutex or spinlock, allowing some increased parallelization.

  • Patent number: 10255341
    Abstract: Various embodiments of systems, computer program products, and methods to provide mode switching in high availability disaster recovery (HADR) systems are described herein. In an aspect, an average commit wait time associated with replicating data from a primary database to a replication database is determined based on a previous average commit wait time and a current commit wait time. A counter is incremented when the average commit wait time is greater than or equal to the predefined maximum commit wait time. Further, a check is made to determine whether the counter is greater than or equal to a predefined threshold and whether a predefined timer associated with the counter is expired. When the counter is greater than or equal to the predefined threshold and the predefined timer is running, the primary database is switched from a synchronous mode to an asynchronous mode for replicating the data.

  • Patent number: 10250693
    Abstract: A method, machine, and computer-readable medium is provided for managing transactional sets of commands sent from a client to a server for execution. A server receives, from a client in a second session, a request that identifies a set of commands that were sent by the client in a first session. The set of commands comprises one or more transactions. The server determines that at least one transaction of the one or more transactions in the set of commands has not committed. Based at least in part on determining that the at least one transaction of the one or more transactions has not committed, the server blocks, from the second session, completion of the at least one transaction in the first session to prevent committing of the at least one transaction in the first session.

  • Patent number: 10031917
    Abstract: The illustrative systems and methods use a special-purpose volume-replicating server(s) to offload client computing devices operating in a production environment. The production environment may remain relatively undisturbed while production data is replicated to a geographically distinct destination. Replication is based in part on hardware-based snapshots generated by a storage array that houses production data. The illustrative volume-replicating server efficiently moves data from snapshots on a source storage array to a destination storage array by transferring only changed blocks for each successive snapshot, i.e., transferring incremental block-level changes. Periodic restore jobs may be executed by destination clients to keep current with their corresponding source production clients. Accordingly, after the source data center goes offline, production data may be speedily restored at the destination data center after experiencing only minimal downtime of production resources.
